Title:
DCCDC CONVERTER CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPS5543946
Kind Code:
A
Abstract:
PURPOSE:To set the feedback control of a DC-DC converter with one circulation gain constantly by setting the output characteristics of a control signal generator to become a function of a feedback signal when the converter conversion characteristics are given as the function of the control signal. CONSTITUTION:This system comprises an error amplifier A for generating a feedback signal y on the basis of the difference betweent the output voltage Eo of a DC-DC converter (CNV) having nonlinear conversion characteristics and a standard voltage VR, and a control signal generator circuit (PWM) for generating an output signal represented by a function g(y) with respect thereto when a feedback signal is given. When the conversion characteristics of the converter (CNV) is given by the function f(x) of the control signal x, the output characteristics of the generator PWM becomes as the following formula as to the function of the feedback signal y (where K represents constant). Thus, it can retain the one circulation gain of the feedback control of the converter having any conversion characteristics constantly to stably control the converter.
